Qt Creator Clang Code Model can't find included header in included header

Question

My problem is as follow: The clang code model from Qt Creator is unable to find the first header included in the header file of a cpp file.

CPP-File:

Header file of that cpp-file:

As you can see, the code model has no issues finding QDialog in the header file, but has so in the cpp file. I have the same issue in other files too. The project compiles without problems too. I already deleted the cache files in my build folder and reindexed all again. I can't find the log files of clang tho.

Do you have this in your cmake file? – László Papp Jul 27 '22 at 17:28 — László Papp, Jul 27 '22 at 17:28
Yes, I do. The program compiles without any errors – ChaoticHans Jul 28 '22 at 07:55 — ChaoticHans, Jul 28 '22 at 07:55

Disabling unity build fixed it.

Sometimes clandg code model gets lost when updating QtCreator or changing its compiler settings. Last time

Removing %APPDATA%\QtProject
Removing %LOCALAPPDATA%\QtProject
Re-creating the project from scratch

has fixed the problem for me.

(The paths above are for Windows. For other platforms see Where QtCreator stores its settings and kits)
